JEE PHYSICS MCQ: CURRENT ELECTRICITY

Analyzing +4 | -1

Assertion: As a direct current passes through a thick metallic conductor, it produces magnetic field only outside the rod.
Reason: Current passes only along the surface of the conductor and not through the interior.

View answer and explanation

Correct option: D

If both Assertion & Reason are false

Option D is correct because both the assertion and the reason are false. Direct current flows throughout the conductor, not just on the surface, and it produces a magnetic field both inside and outside the rod.
